If that's really the case, wouldn't Jason Bay theoretically have a freakish OBP too? Or, say, Aubrey Huff? The #1 slugger on crappy teams aren't putting up the OBP numbers and showing the patience Dunn is. I think you're slighting him. I'd expect Dunn's OBP to remain consistently high as a Cub. And if Dunn hits a bunch of solo shots, well, that's the Cubs' fault for not getting on base ahead of him.
